I have recently given two IM injections into the upper outer quadrants of my buttocks. The mix was 1cc Deca and 1cc Sust. Usually I have a sore hard knot for 1-2 days after an injection. This time the site became red, inflammed, very hard, and increased in size 3-4 inches across the ridge of my butt. The injection is now weeks old and the problem remains. Do I have bad stuff, is this an infection, or an allergic reaction? I hate to quit this early in my cycle but this is starting to make me nervous. Any thoughts!!!
